Maximizing ship designs

I think it should be evident to everyone that no one builds a fleet to
fail.
There is an entire science called naval architecture devoted to finding
the
best and optimized fleet design of ships.  The problem is that you have
multiple missions for ships to accomplish and so balances have to be
struck.
And again there are different mindsets to how to accomplish them.  So
unless
you desing a campeign or scenario that has these competing missions,
ships
will be optimized.  Legislating your versionof sanity won't change it.
